i have no idea how to use this so can someone explain it and i've looked it up and not really sure of the options etc
now the main reason is my app consit of alot of prx's can psp-addr2line find out which file/line the problem occured on if it occures in a prx and not in the main
how can i use psplink with eclipse on ubuntu 9.04 to debug this app with its prxs because debugging is becomming a pain
psp-addr2line question / help
When you use PSPLINK and your app is crashing you gat an exeption.
If you type right after the crash:
calc $epc-$mod
you get an number like:
0x00015A45
Now you can run:
psp-addr2line -e appname.elf 0x00015A45
The program will output the line in your code which causes the crash.

}well i added -g option and got this when trying to compile
got that same error above with the relocation and i cant figure out how to fix any suggestion would be appreciated
